What Climate Science Tells Us, What It Doesn’t, and Why It Matters | Steven Koonin

Hidden Forces

In Episode 187 of Hidden Forces, Demetri Kofinas speaks with Steven Koonin, author of “Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters.” Dr. Koonin serves as Director of NYU's Center for Urban Science and Progress. He previously served as Undersecretary for Science in the U.S. Department of Energy under Barack Obama and as Chief Scientist at BP, where he was a strong advocate for research into renewable energies and alternative fuel sources.

The science of climate change has become, like almost everything else, a matter of political identity in 21st century America. A recent Pew Research study found that Democrats are more than three times as likely as Republicans to say that dealing with climate change should be a top priority. And yet, if you ask people independent of party affiliation for their views on climate change and why they believe what they believe, most of them will struggle to give you a coherent answer. In fact, very few people, and this goes for politicians, journalists, and even academics, have actually read the reports put out by organizations like the IPCC and others responsible for doing the actual research that we all cite when we talk about “the science.” And to be honest, can you blame them? Afterall, why would anyone want to spend a minute of their time learning about exactly why we are so screwed? About how we’ve destroyed the planet and “broken the climate?”

We’ve read all the headlines. “Climate Catastrophe.” “Climate Disaster.” “The earth is burning!” But how true is this, exactly? Are we really facing a “Climate Apocalypse?” Is climate science really “more reliable than physics,” something that journalist David Wallace-Wells said in a recent appearance on the Joe Rogan Podcast. Not according to my guest, but more importantly, not according to the science, which, to borrow from the book’s title, is very much “Unsettled.”

Before you react to that very provocative book title, you should know that no one is saying climate change is a hoax or that anthropogenic warming isn’t real. The purpose of this conversation is not to surreptitiously undermine the consensus view or to troll those who believe strongly in it. Rather, it is simply meant to help inform those of you who either haven’t read the reports or are simply skeptical about just how bad the situation is and what’s required from us in order to solve it. This is a subject that deeply concerns all of us, but the doom and gloom narrative surrounding it has arguably become counterproductive in helping us actually address the problem.

Steven and Demetri spend two hours—between the first half and the overtime—working their way through the data, what it says, and what the models predict about not only future warming, but also the incidences of droughts, forest fires, hurricanes, rising sea levels, climate-induced migration, and pandemics driven by a warming planet.

In the subscriber overtime, they focus most of their attention on the incentives that account for these widely divergent narratives on climate, the importance of morals and values in thinking about how to structure climate policy, and the missing components of costs and tradeoffs that we all need to think about when coming to decisions on how best to adapt our societies and ourselves to the changing climate.

Kofinas and Koonin also discuss geoengineering, including carbon extraction and the use of aerosols to dampen the sun’s rays, as well as alternative sources of energy like wind, solar, and nuclear, and their respective roles as alternatives to fossil fuels in the coming decades.
